The disciplinary committee of the ANC has decided to expel former president Jacob Zuma for leading a rival group into elections in May, several media reported Sunday, citing a leaked document.
The decision, which has not been formally announced, was taken after disciplinary proceedings launched against the still-popular ex-leader earlier this month.
"The charged member is expelled from the ANC," says the leaked document, also seen by AFP, that is dated July 29.
"The charged member has the right to appeal to the National Disciplinary Committee of appeal within 21 days."
The African National Congress suspended the scandal-tainted ex-leader in January, a month after he endorsed the newly formed uMkhonto weSizwe (MK).
MK cut into the ANC's share of votes in the May 29 elections, taking third place with 14.5 percent. Zuma now leads the party, which has 58 lawmakers in the 400-seat National Assembly.
The ANC managed 40 percent in the May vote, its weakest score since it came to power three decades ago to replace the apartheid government.
Barring a successful appeal against the ruling, Zuma could have his ANC membership terminated, several media reported.
He joined the ANC via its youth league as a teenager in 1959.
Elected South African president in 2009, Zuma was forced from office in 2018 under the cloud of corruption allegations and was replaced by long-term rival, President Cyril Ramaphosa.
The charismatic and outspoken 82-year-old still carries considerable political clout in South Africa, even enjoying support within some factions of the ANC.
Many believed his political career would end when he was sentenced to 15 months in jail in June 2021 after refusing to testify to a panel probing financial corruption and cronyism under his presidency.
His imprisonment triggered riots that sparked South Africa's worst episode of violence since the fall of apartheid, leaving more than 350 dead.
He spent only two months behind bars and was released for health reasons, after which Ramaphosa commuted his sentence.
A damning 2022 report concluded that Zuma had played a central role in state corruption during his nine-year tenure.
